Tunze Safety Connector Question/Issue

[BraenDead]

I finally found a battery and charger locally to use with the safety connector. I wired everything up yesterday and today I tried it out with my Tunze 6055 and it did not work. When I say it did not work, I mean the 6055 didn't spin at all.

I have it wired as follows:
- The battery (12V, 12Ah) is connected to the charger and to the safety connector
- The 6055 power supply is plugged into the safety connector
- The safety connector is plugged into the 6055

When I remove the safety connector from the equation the 6055 spins as normal, works without problems. The battery is fully charged (12V, 12 Ah), if that makes any difference.

Looking for some help here, would love to get this going!

As an additional note, I tested the voltage on the battery input connector of the safety connector to verify that everything is correct. It is reading 13.30V, so no problems with the wiring.

Appreciate any help!

Problem solved - the fuse was loose. I didn't realize the fuse is popped out when loose and can push in to tighten it up. It's working off of battery now, testing to see how long the battery can power this!

So, what was the result?

 

[BraenDead]

Still going on battery...

 

[rvitko]

What size battery? How long has it been?

 

[BraenDead]

Running a 6055 on a 12Ah 12V battery since 6:20PM CST yesterday. Multimeter read 13.3V on the battery and the battery is brand new, should theoretically be able to get ~30 hours.

Still going.. over 38 hours now...

Finally stopped... Total of 40 hours of runtime - much better than I expected! Now to see how long it takes to charge the battery back to full

So I take it this is a small gel cell type battery?

 

[BraenDead]

The battery I used is a Werker AGM sealed lead acid battery, this one specifically:

I bought a Battery Tender 800 mAh waterproof charger, this one specifically:

With tax they were $92 at my local Batteries Plus store. Not bad for the peace of mind it offers.

40 hours, that's pretty good. Looks like I need to run over to Batteries Plus

Great post, Bob. Thanks for sharing!

I have the exact same battery as Bob from my local Batteries Plus and interestingly enough, it ran 40.5 hours as well on my 6055. It took less than a day to charge back up.

More than enough time to get home and hook up the generator.

I'm looking to run two 6055's for two or three days. Am I better off using a 12v or a 24v battery or should I just be looking at the AH rating.

If costs not an issue what type of battery would work the best.

 

[BraenDead]

12V will run the pumps at low speed, 24V will run them at full speed, so it really depends on what speed you want them running (obviously 24V requires a bigger battery for the same runtime).

Your best bet if space is also not an issue is to use a good marine 12V battery.

Thanks, Bob. Your input was a big help.

Crypsis, what did you end up getting? I, too, am looking for maximum backup duration.

What do you do for Heaters?

 

[BraenDead]

Heaters aren't a concern for me, a day of somewhat cooler temp won't be much of a concern. If it were several days, about the only solution is a generator.

Heaters take so much wattage/current a battery just isn't going to last that long.

If you have a gas hot water heater, you can fill up zip locks with hot water and float them in your tank when the power is out. I've done this before, but it takes a lot of refilling the bags to raise the tank 1 degree.

No gas hot water heater? I guess the bbq is more tricky, but if it were all I had...
